Abstract

Data from the Coma, Perseus, and A 1367 clusters are taken together with data from QSS to provide information on slope and location of redshift-magnitude bands. Both slope and location are found to be fairly constant in comparisons of one cluster with another. An analysis of the Perseus cluster shows a distinct change in redshift-magnitude and mean redshift with radius. This radial brightening trend is applied to observations of the Coma cluster, as well, noting that the outer part of the cluster contains the same band pattern as the core. The analysis is also extended to low redshifts in an attempt to construct an empirical model of band and galactic evolution.
